The AK-74 (7.62x39) muzzle brake reduces felt recoil up to 55-70% and reduces muzzle
climb up to 75-85%. The AK-74 Muzzle Brake screws on to threaded barrels. The
brake reduces muzzle climb by directing gas upward through three gas ports. The
recoil is diminished by open gas ports which direct gas away from the weapon
sideways. The two gas streams cancel each other and absorb the force of recoil.
